Homebrew Website Club Düsseldorf

At the recent beyond tellerrand conference, I got to chat with Daniel Pietzsch and Christian Schäfer about the IndieWeb camp. We ended up talking about how I'd been wanting to get more involved with the IndieWeb community and had even been thinking about starting a local Homebrew Website Club. Turns out they'd been having the same thoughts! They'd already organized a first meetup, which happened last week (there's even a nice group selfie 😊).

It was great fun discussing all things IndieWeb and sharing what we've been working on with our personal sites. We dove into topics like IndieAuth, how to handle photo integration, and the eternal debate between static site generators (which most sensible people there prefer) versus my maximalist approach of running a full web stack on my own server. Call me old-fashioned, but "serverless Postgres" just sounds wrong to me. Either way, this gives me the perfect excuse to dust off django-indieweb and get it up to date again—really looking forward to it.

PyDDF Spring Sprint

I spent the weekend at this year's PyDDF spring sprint. My plan was to experiment with MCP (Model Context Protocol) and get back into working on django-resume. I figured I'd replace my old few-shot approach for generating new plugins with a shiny new MCP version.

I managed to get an MCP server up and running, but things didn't go as smoothly as I'd hoped. The model kept going down these long, winding rabbit holes that led nowhere. I even gave Claude Desktop access to the website through a Playwright MCP server, thinking it could verify whether the plugins were working correctly. Instead, it started trying to enter data through the Django admin (which I never suggested) and attempted all sorts of bizarre workarounds. More often than not, it would hit the token limit and all that effort would be for nothing. Though I have to admit, it was pretty impressive watching it try so hard to reach its goals.

I'm starting to question whether MCP servers are really the right approach for coding assistance in my specific django-resume "create a new plugin" use case. They seem much trickier to get right compared to few-shot learning for this particular scenario. Plus, I'm mostly using Claude Code these days anyway, which works great—I can just ask it to write a plugin without needing any special tooling. The one remaining use case I can think of would be using django-resume as an MCP client that could dynamically display generated forms on the site. But that would be significantly more work. Not sure if I'll pursue it, though it might be a good learning experience to build a sampling client.

KptnCook

Nero3ooo developed a helpful Progressive Web App (PWA) frontend for my KptnCook scraper. This is particularly useful if you use the KptnCook app on your smartphone and want to save recipes for later. Now, you can simply use the share button in the KptnCook app to share recipes directly with the PWA. I feel a bit guilty about neglecting KptnCook lately, as I've been so busy. I really should maintain it more actively 😅.

Progress Update on Vibe Coding Project

I've made significant progress on my vibe coding experiment (Nyxmon). The monitoring agent is now running fairly stably, so I decided to create a dashboard to display all the checks in one place. To make use of the empty space, I added a progress ring that shows when each check will run next. Users can manually trigger checks or disable them as needed. While it looks like a modern single-page application, it's actually a traditional multi-page application that uses htmx and some web components running on a Django backend. My next steps will be implementing more sophisticated checks that go beyond simple HTTP status monitoring—like analyzing JSON responses or supporting other protocols such as ICMP.

Beyond Tellerrand 2025

btconf opening hippo lamp

I attended the Beyond Tellerrand conference in Düsseldorf this year. Being local residents, my partner and I didn't have to travel far to the venue, and since we're both interested in the topics, we always attend together. In previous years, we'd bring our children along, taking turns watching them between talks. This year marked the first time both kids were in kindergarten or school in the mornings and at playdates in the afternoons, so they didn't join us. Several attendees actually noticed their absence and asked where we'd "left the little ones."

The conference was excellent as always. I gained plenty of inspiration and thoroughly enjoyed both the presentations and conversations with familiar faces and new acquaintances alike. I did find myself wondering if the conference might benefit from exploring even more diverse topics "beyond tellerrand." It would be fascinating to see someone like Simon Willison discuss AI and its implications, or perhaps dive into more technically in-depth backend topics that could bring fresh perspectives.

That said, I can't recommend Beyond Tellerrand highly enough! The event consistently delivers exceptional content in a welcoming atmosphere that encourages creativity and connection. If you haven't experienced it yet, you're truly missing out on one of the best web conferences in Europe. And if you can't make it yourself, definitely encourage a colleague or friend to go – they'll thank you for it!

Special shout-out to my fellow podcast colleagues who made this event even more enjoyable: Alexander Bürner (devslove.it), Christian Schaefer (Working Draft), Sarah Gross (wwsiv) – and to Daniel Pietzsch and Nik Rademacher – it was fantastic seeing all of you there!

Nyxmon

I've made significant progress with my experiment developing a minimalist monitoring tool using vibe coding. I now have a comprehensive integration test where I add a check to the database and launch a check collector in a separate thread. This collector uses a blocking portal to poll the database for checks that are due to run.

Once a check is identified, the system issues an "execute checks" command that leverages an async check runner adapter along with another blocking portal. This setup allows the pending checks to run via httpx async in the event loop before returning results back to the synchronous message bus through a callback.

After receiving the result, the system issues an "add result" command to the message bus. Then the SQLite repository adapter utilizes a portal to write the result to the database within an async context.

While the code structure appears somewhat complex, it seems to be functioning as intended. The architecture successfully bridges synchronous and asynchronous operations throughout the monitoring workflow.

django-cast

Just released a new version with official support for Wagtail 7 and Django 5.2.

I'm not passive aggressive unlike *some* people --Benack OBena

Getting back to work after a conference week. Barely had time for anything else. Made it to the beyond tellerrand warm-up event and heard some heartwarming stories about the indiewebcamp, which I unfortunately missed. Hoping to attend next year.
